The present invention relatesi toV a valve and more particularly to afaucet-type valve.

The primary object of the invention is to provide a valve in which theliquidv pressure exerts a; force on the valve parts toseat the same whenthe' valve is closed.

Another object is to provide a valve of the rotary cylinder type for useas a faucet in bath tubs, sinks and the like, which can be convenientlyand accurately controlled and which requires very little attention sincevalve washers and similar elements are eliminated.

Another object of the invention is to provide avalvewh-ich is extremelysimple and inexpensive to manufacture.

Other objects andv advantages of the invention will become apparentduring the course ofV the following description ofthe accompanyingdrawing, wherein:

Figure l is a vertical sectional View of the valve embodying theinvention, showing the same in a closed position; Y

Figure 2 is a similar view but showing the valve in an open position;

Figure 3 is a horizontal cross-sectional view taken on line 3-3 of.Figure l looking in the direction of the arrows;

Figure 4 is a horizontal cross=sectional view taken on line 4 4 ofFigure 2; 't j Figure 5 is a perspective viewof the valve cylindershowing the circumferentially-spaced openings therein: Y

Figure 6 is ay fragmentary perspective view of the lower end of thecylinder-operating o r valvecontrol shaft showing the radially-arrangedarms thereon to provide coil spring seating surfaces;

Figure 7' is a perspective view of one'of the arcuate sections of thevalve, showing the general shape thereof.

In the drawing, and more in detail, there is shown a Valve casing orhousing generally designated 5 and a valve cylinder generally designated6. The valve cylinder (i is rotatably mounted within the valve casingand arranged to control fluid flow therethrough.

The Valve body comprises a body portion 'I open at both ends and ofcylindrical shape and is formed with a central longitudinal opening 8therein. The cylindrical valve body I is externally threaded at bothends as at 9 and I0, and an annular boss I! is formed integral with thebody to provide a limiting stop when the threaded end 9 of the same isscrewed into an outlet tting. The annular boss is also provided withwrenchengaging faces to enable the' body to be applied to such fittingsor pipe ends.

The upper portion of the valve body bore 8 is slightly enlarged indiameter as at I2 to form a Valve chamber, and formed in the valve-.bodyis an annular outlet ow chamber I3 in communication with the interior ofthe valve body bore 8 by a series of circumferentially-spaced openingsI4, Figures 3 and 4, arranged 120 apart.

Formed integral with the valve. body I is an outlet spout |5 having adownwardly-directed nozzle I5, and said spout is in liquid flowcommunication with thek annular outlet chamber I3 as clearly shown inFigures 3 and 4.

Rotatably mounted within the enlarged portion I2 of the valve body bore8 is the valve cylinder 5 which comprises a shell-shaped body, open ateach end The valve cylinder is machined on its outer peripheral surfaceto frictionally androtatj-. ably engage the inner periphery of theenlarged portion I2 of the valve body bore B, and has its lowerendseated on the shoulder 2l! formed by the said enlarged bore I2. to limitdownward movement of said cylinder. The valve cylinder i5V may be. madeof two, three or more partis. As shown in Figure 5, the valve cylindervis formed of three arcuate sections or par-ts 36:, 31 and 38 made ofrigid metal or any other suitable mate rial. Each of the sections isprovided with a pair of' cut-outs 39, Figure '7, at its. side or meetingedges and when the sections 3,5-, 3,1. and 3 3 are. 21S'.- sembled toform the. valve cylinder t, the cut-:outs SiS: coact to dene threeequally-spaced Openings 4i! which are adapted to move into and out o fregistry with the. spaced openings i4 in the valve bodyy upon rotationof the valve cylinder For turning the valve cylinder` 6, there isprovided' an upwardly-extending operating shaft 2! which projects intothe. interior- Of the Cylinder 6 centrally thereof. An operating handle23 is affixed to the upper end of the operating shaft 2 I, and formedintegral with or secured to the lower end of the shaft 2l is a series ofequally-spaced, radially-extending, cylindrical arms or pins 24. Theouter ends of the arms 24 are received or seated in holes 22, Figure 5,which are formed -by the adjacent cut-outs 4I, Figure 7, in the meetingedges of the arcuate sections V3B, 31 and 38 when the latter areassembled to form the valve cylinder 6.

A series of coil springs 30 are arranged with in the valve cylinder 6 sothat each coil spring will encircle the radial projecting pin 24. Thus,the coil springs will yieldingly urge the arcuate valve cylindersections 36, 3'! and 38 into frictional contactual engagement with theinner peripheral surface of the valve body bore I2.

Mounted on the upper end of the valve body 5 is a bonnet 32 having anannular ilange 33 internally threaded for being received on thecorrespondingly threaded portion i of the valve body. A central opening34 in the valve bonnet 32 accommodates the control shaft 2|, and apacking disk 35 having a central opening likewise for accommodating thecontrol shaft is interposed between the valve body and bonnet 32,respectively. The .packing disk 35 also' engages the top of the valvecylinder and prevents escape of liquid 110W between the valve cylinder,valve body and bonnet structure. A cap nut 42 is threaded into the upperportion of the bonnet 32, and the operating shaft 2i rotatably ntsthrough the nut and packing 43 arranged therebelow.

In operation, the valve cylinder is turned by rotation of the controlshaft 2l in either direction of rotary movement about the axis of thecylinder E so that when'the valve is in a closed position, Figure 1, theopenings 40 in the valve cylinder 6 will be out of registry with theports I4 and arrest fluid now through the valve. If the control shaft 2lis rotated an angular distance of 60 in either direction from that shownin Figure l, the openings 40 Will be brought into registry with theports l and permit liquid flow through the valve and faucet spout i5.

By reason of the fact that the valve cylinder 5 is arranged on theinterior of the valve body enlarged bore l2, the Water pressure willexert a force in addition to the yielding action of the coil springs 30to seat the valve cylinder when the valve is closed, and thereby form atight liquid seal without necessitating the use of iieXible washers orother sealing valve elements which quickly disintegrate under varioustemperature conditions and require frequent replacement over relativelyshort time periods.

It is to be understood that the form of the invention shown is to betaken as a preferred embodiment of the invention and that variouschanges in the shape, size and arrangement of parts can be resorted toWithout departing from the spirit of the invention or the scope of thesubjoined claims.

I claim:
